Mich., a corporation of New Jersey i Application March 28, 1938, Serial No. 198,457 1 Claim. (Cl. 98-37) The present invention relates to air-conditioning apparatus; and its object is to provide such an apparatus for supplying pure air of proper temperature to rooms, as theatre auditoriums and the like, which shall be simple and economical in construction, readily installed, effective in operation, and particularly, which may be readily mounted in connection with the chairs in such auditoriums.

This and any other objects hereinafter appearing are attained by, and the invention finds preferable embodiment in, the illustrative apparatus and the Variousparts thereof particularly described in the body oi this specificationand illustrated by the accompanying drawing, in which:

Figure 1 is a View in perspective of a damper and the mounting therefor;

Figure 2 is a side View thereof shown partially in section taken on line 2--2 of Figures 1 and 3;

Figure 3 is a plan view of the damper and a sectional view of its mounting taken on line 3-3 of Figures 2 and 4;

Figure 4 is a transaxial sectional view of the same taken on line 4-4 of Figures 2 and 3;

Figure 5 is an elevational view in perspective of portions of an air conduit, mounting means therefor and a damper with its mounting in the conduit, a portion of the floor through which the conduit extends being broken away;

Figure 6 is an elevational View thereof, the 1100 being shown in vertical section taken on line 6-45 of Figure 5;

Figure 7 is a horizontal sectional view of parts shown in Figures 5 and 6 taken on line 1-1 of.

these views.

In the drawing my apparatus is shown in connection with a room-a theatre auditoriumfor air-conditioning the same by supplying pure or clean air of proper temperature thereto or withdrawing impure air therefrom.

A conduit for the air is shown extending through a wall--the floor l-of the room, comprising an inner portion or section 2 in the floor and an outer portion or section above the floor,

this outer section, in the room, comprising sepa- 1, 8 and top walls 9, I0 respectively, the side walls of the outer (upper) portions 6 curving in an arc of greater radius than that of the curvature of the side walls of the inner (lower) portions 5, asbest seen in Figure '7. These side walls have air passages II, I 2 therethrough. The halves,

assembled with their concave sides mutually adjacent and connected by a bolt I3 extending therethrough provided with a nut l4, are held in place by and between a pair of supporting members i9, extending parallelly from, and fastened as by screws IS on, the room side of the wall or floor, the vertical edges E6 of these halves engaging behind a pair of opposite vertical ribs ll of said members as indicated in Figure 7, the said members being the leg portions of a standard 2! supporting the seats and the backs of a pair of sidewise adjacent chairs (not shown) in the auditorium. I

In the circular lining 22 of the inner section 2 of the conduit (which extends through the floor) a damper with its mounting is removably seated between said members I9, 20 and is turnable therein for directing the air issuing therefrom.

This mounting comprises a pair, of diametrically opposite downwardly extending arm portions 23 having ledges24 resting on the floor or on the upper edge ofthe lining 22, and connecting upper and lower cross bars 25, 26. forming stops for limiting the turning movement of the. damper as indicated in Figure 4.. A spindle 2'! seated in openings 28 inthe arm portions 23 extends diametrically through the damper 29 between its oppositely extending ears 30, 38 with a coiled spring 32 surrounding the spindle and pressing between one of the arm portions 23 and the edge of. the damper to frictionally hold the same in turned position.

It will be seen that myair-conditioning apparatus may be readily installed in theatre auditoriums and the like, the outer upper section of the conduit being removably held by and between the leg portions of one of the standards of a chair therein; and that thus installed the said section is located in a position wherein it interferes slightly or not at all with ready access to the chairs and occupies little space in the auditorium; and that the parts of the apparatus may, when necessary or desirable, be readily removed and replaced.

The invention being intended to be pointed out in the claim, is not to be limited to or by details of construction of the particular embodiment thereof illustrated by the drawing or hereinbefore described. A

I claim:

An apparatus of the class described forconditioning the air in a room furnished with chairs having spaced legs: an air conduit comprising a cr'oss-sectionally circular section extending through the floor of the room and a section in the room comprising separate lateral halves having concavo-convex side walls with air passages therethrough, the mutually adjacent opposite vertical edges of said halves assembled with their concave sides mutually adjacent being engaged by said legs for holding said halves between them;

a damper turnable to conduit closing and opening positions; a mounting for the damper turnable in the first mentioned section, comprising downwardly extending arms connected by cross bars, a spindle for the damper supported at its ends on the arms respectively and ledges resting on the floor to support the damper and its mounting turnably'on the floor.
